Keg still column build

[tag1260]

Is there any practical difference between a 2 inch column that has a 2 inch 90 on top vs one that doesn't and goes straight into 1/2 inch? Thanks

What type of still are you asking about?

[tag1260]

Pot still from a keg.

No problems at all for a pot still. I used to have a pot still just like that and was getting 3-4 lph running a 2200W element 240VAC on stripping runs.

kimbodious is right, it's not an issue with a basic pot still. If you look at a lot of pics of well built pot stills, you'll see that they often have two elbows and a connection between them. That allows the product condenser to be set at any angle. Often people use copper Unions or Tri-Clamp connections.

Often people use a 2" elbow and a reducer to the connection because it looks cool though it isn't required in order to function just the same.

Ok. My question is answered but what I'm asking is the difference between using a 2 inch vs 1/2 inch 90 at the top of the column.

Basically dollars, you will have to make a reduction to 1/2 at some stage and because you are reducing to half inch I'm assuming you are going to run a liebig or worm.
So the economics of it are basically do I pay for a 2 inch 90 or a 1/2 inch 90.
Have a look at the potstill thread for different heads
Or this has a heap

You'll get more use out of your parts if you build your still with 2" tri-clamp connections and 2" components, then reduce to 1/2" after your elbows. That way if you want to change things up down the line or decide to switch to a shotgun, all you have to do is take off the liebig and it's plug and play from there.

The extra expense (in my opinion) is worth it when it comes to versatility. You won't have to rebuild your riser when/if you want to reconfigure.
